My friend Colin Beavan is known as the "No Impact Man" for his enviormental conservationist and activist lifestyle. He set out on a project five years ago to change his life by living a more green-life in New York city. Colin and his family didn't live with electrity, road bikes, walked nine flight of stairs to their apartment and many other changes most people consider impossible to make. Collin's mission to wake people up, on an individual and collective level, to a ways of life and doing business that are healthier and happier for individuals, society, and our world.
